Valid complaint, but I have to imagine it's probably ridiculously easy to just change some values and slap some icons in there for this. Also the people who care the most about this also include the people who probably bitch the most, but will still play and eat the shit out of more prestiges.
No, the people who care the most are the people who don't want to be yet another douchebag using the same guns everyone uses.
For example, I had taken a break from the game up until I found out that they released a patch for the shotguns. The KSG and USAS were no longer a pain in the ass until level 23. As a result I started finding the game fun again.
Unfortunately, as time went on, it became more and more apparent that whatever buff the 1887 and spas-12 got weren't enough and the AA-12 was still the same gun that forced you to use scavenger and steady aim to do decently. I just recently tested the spas-12 and the gun still does only 30 damage close range per pellet. It's a total buzzkill to find out that the patch that was supposed to buff all of the shotguns (besides the striker) couldn't even do that.
Personally I'm taking a break until they do at least one of the following:
a) buff the LMGs
b) buff the spas-12, 1887, and AA12
c) buff the PM-9 and MP5
